Codeigniter form-> run（）相当于form_validation-> run（）？

Question

I'm relatively new to CodeIgniter and this may be an obvious answer, but I am unable to find anything in the documentation.

I know how to use form_validation->run() to validate a form and run some code when it is submitted successfully. What if I wanted to do something with a form that did not require any sort of validation? Is there a form->run() equivalent that returns true when a user submits the form? Something like:

page.php

public function update($id)
{
    $this->load->helper('form');

    if($this->form->run())
    {
        // do some stuff after user has submitted form
    }

}

I don't think there exists such method, but you can do it manually For example:

if ( ! isset($_POST['something']))  // OR $this->input->post('something');
{
    return false //maybe?
}
else
{
    //$something = $_POST['something'];
    return true //maybe?

}
